Olivia Munn's character in “I Don't Know How She Does It” calls Justin Bieber - born to a teen mom - a "billion-dollar mistake." Facing Belieber backlash, Munn explained the joke to Access Hollywood.

"Look, Justin Bieber was a mistake,” Munn, 31, said of the crack. (Bieber’s mom, Pattie Lynn Mallette, was 18 when she gave birth to the future superstar.) “Teenagers don't get pregnant on purpose, OK? However, that mistake turned into a billion dollar idea!"

The actress also added that perhaps if more teenagers procreated, their resulting pop star progeny could save our economy. (Um, has she seen “Teen Mom”?)

“Teenagers around the world, load it up!" Olivia told Access. "Let's make some Biebers! The economy needs a little boost. Let's make some Biebers!"

But joking aside, the actress is a fan of the Biebs. "I'm a Belieber, 100 percent," Munn said.

It was Olivia Munns character in a movie, who made this statement! That means some1 else wrote the words & a director told her to say them! PC police & hatered aside, it's important to have all facts straight, otherwise you'll be taking things out of context!!
